**No areas of concern across the Atlantic that would affect the U.S. or any other land areas **
However, tropical storm Sebastien has formed over the Central Atlantic 300+ miles east of Puerto Rico. Sebastien will drift to the northwest before merging with a frontal system & accelerating northeast late in the week. Once merged with the cold front, transition to an extra-tropical low pressure system will occur over the open North Atlantic. No impact on the U.S. & the system will stay south & east of Bermuda. Marginal atmospheric conditions - northwest shear in particular (satellite imagery shows most of the t'storm activity to the east of the low level center) - will keep the tropical storm from strengthening a great deal though there may be a brief uptick Wed./Wed. night about the time Sebastien is absorbed by the frontal system.
Less than two weeks are left in the Atlantic hurricane season! Two hurricanes have ever made a U.S. landfall in Nov. - both in Florida: "Yankee" on Nov. 4, 1935 - at Miami..... & "Kate" in the Panhandle on Nov. 22, 1985.
Other notable storms include "loopy" Gordon in 1994... Lenny in 1999... Paloma in 2008 & Ida in 2009.
2019 names..... "Tanya" is next on the Atlantic list (names are picked at random... repeat every 6 years... historic storms are retired (Florence & Michael last year) & Dorian is almost certain to be next:
